SEWING-MACHINE.

To all whom it may concern: I

which the following, taken in connection with the drawing, is adescription My invention relates to certain improvements in sewingmachines, which may be applied to various makes of machines, and hasreference more especially. to the bed plate, throat plate and feedmechanism, and which consists of certain novel forms of construction andarrangement hereinafter set forth.

The primary object of the invention is theco-nstruction of a bed plateof the class described in my Patent No. 884,482, issued April 14, 190 8,which when closed will present the same flat smooth surface of anordinary machine upon which any kind of sewing may be done, and whichcan,.with out removing any fastenings or other parts of the machine bechanged into a sectional bed plate, whereby circular garments such asstockings, sleeves, bands, or the like, which it is impossible to sew ormend upon the flat plate, may he slipped over one section of my improvedbed plate and be directly beneath the needle and can be as, readilysewed as a straight seam.

A further object of my invention is to so construct the bed plate thatthe sewingv mechanism, Whether in a lock stitch or a chain stitchmachine, will be arranged to extend parallel with the arm of themachine, and to be encompassed within a small space and completelyincased so that none of the parts are exposed or liable to come intocontact with the material being sewed.

A further object of my invention is to provide a threat plate which isvery simple, in construction, but which is adapted to be, used forsewing light or heavy material with. fine or coarse thread and may beused on either a lock stitch or chain stitch machine, and after beingonce adjusted in. place it is not necessary to remove the same in orderto arrange the machine for different kinds of sewing.

Other objects and advantages of construc tion will be hereinafterpointed out and Specification of Letters Patent.

claimed iu'the following description.

Patented Dec. 3/, 1913.

In the accompanying drawings I have shown what I now consider to be thepreferred form of my construction, although it is obvious that detailsthereof, and the size and relative proportionsof the parts may bechanged without departing from the spiritthereof, and in. these drawingsFigure 1 is a side elevation of the bed plate and the mechanismincl-osing casing beneath it; Fig. 2 is a plan view partly in section;Fig. 3 is a sectional view taken on line 33 of Fig. 2 showing the slidepushed back and the bed plate open; Fig. 4 is a like view taken on thesame line, but with the slide'closed; Fig. 5 is a sectional view of aremovable block in the table of the machine, taken on line 11-11 of Fig.2; Fig. 6 is a section through the throat plate; Fig. 7 is a sectionalview of the bed plate taken on line 88 of Fig. 2; and Fig. 8 is asectional view of the end cap of the inclosing casing.

A represents the bed plate of the machine, which is preferably made ofmetal, although any material suitable for the purpose may be employed.

is the head of the machine which is mounted upon the rear portion of theupper face of the bed plate which may he of any well known form ofconstruction to support the necessary operating mechanism, and whichalone forms no part of my invention, therefore no detailed descriptionthereof will be given.

Disposed beneath the bed plate is the no possibility can the materialbeing sewed come in contact with said mechanism.

The bed plate A is provided upon each side of the longitudinal centerthereof with an elongated opening a, a, extending parallel with eachother from the left hand end of the bed plate to the head A of themachine. From the front edge of the head A and beneath the same to therear of the bed plate extending in line with the openings :1, a, arerecesses 7)", b, in which the sliding lates a a are adapted to be movedwhen it is desired to use said openings. Each of these recesses isprovided with a groove (l hereinafter explained. The sliding plates a, awhen closed, form a smooth bed plate as shown in Fig. 4, the slidingplates in this figure being closed while in Figs. 2 and 3 they are movedto the rearward position and the bed plate isformed as shown in Fig.2withthe openings upon either side of'the center thereof. These slidingplates are provided upon each end thereof with .a boss a, a, to limitthe movement thereof in either direction'and which slide in the groovesd upon the bed plate.

B is a removabl'eblock provided with n.

lug 1) upon one end thereof which is adapted to enter a socket in thetable B, which block abuts against the bed plate A and closes the endsof the elongated openings a, a, as shown in Fig. 2. This block isreadily removed from position by grasping I the thumb piece 6 with thefingers'and raising it from the table, whenit isdesired to open the bedplate for special work upon the machine.

Secured to the'top of the bed plate in the usual manner is the throatplate C,

which may be square, rectangular, oval, or.

any shape desired and which is provided with the feed openings 0 and theneedle hole a. The throat plate C is removably attached in the bedplate, and is adapted to .be used with machines having either a lockstitch or chain stitch mechanism.

The inclosing casing A is preferably made of metal and is detachablysecured to the braces A formed uponthe under. side of the bed plate A..The removable end cap D which closes the casing A is held .in' positionby frictional engagement with said casing. As will be observed byreference to Fig. 8 of the drawing, when this cap is secured in placeonthe outer end of said casing A the vertical wall of the cap willbe'spaced from the outer end of said casing, thusformlng a groove orspace d to retain any oil that may drop from the mechanism inhlosed bysaid casing and cap.

ldwsrz' For plain sewing the slides (2 a are.

"The operation of the machine is as foldrawn toward the left and closedand the block B is placed in position so that the machine may beoperated in the usual manner. When it is desired to mend or sew acircular garment, the block B is removed and the slides a a moved to theleft as shown in Fig. 2,leaving the openings (1, (1., upon each ,side ofthe longitudinal center of thelmachine, when the garment to' be stitchedis slipped over the middle section of the bed plate and around thecasing A so that it in said bed plate in 'of a bed plate having side. ofthe removable throat plate secured in said bed the bed plate,

isv free to be moved around said section, or

lengthwise thereof, as desired.

I claim: I I) 1. In asewing machine, a bed plate having longitudinalopenings upon each side of the center of the length of said bed plate,and recesses line with the aforesaid openings, and sliding sections insaid bed plate movable in said, recesses and-openings, substantially asdescribed.

2. In a sewing machine,'the combination;

of a bed plate having a longitudinal opening upon each side ofthe-center slidable mg a groove between the closed end of the cap andthe adjacent end of the casing, as

and for the purpose specified.

4. In a sewing machine, the combination of the table havinga bed platemounted thereon, said bed plate having elongated longitudinally extendedopenings on each longitudinal center thereof, a

plate at the free end of the central section thereof, a casing inclosingthe operative mechanism beneath the central section of table oppositethe free end of said central section and outwardly of the throat plate,

substantially as described.

5. In a sewing machine, a bed plate having longitudinal openings uponeach side of the center thereof, movable slides in said openings, a casesecured to the'under side of the bed plate between the openings, and acap detachably secured around one end of said case with its closed'endat a distance from the adjacent end of the case, thereby forming agroove for the reception of'oil, substantially as described.

In testimony whereof, I have hereunto signed this specification in thepresence of two subscribing witnesses. I
